Hello James,

I don't have access to Moi at the moment, but a look in the file with an Editor shows me, that you used Concat2 for the Points??? Concat2 doesn't support a internal organization/grouping of pointarrays. So in my opinion, it is easier to generate 2 curves for both directions and make then a pattern of the curves. Nevertheless I will try to find some time in the evening (CET) and have a deeper look in the files.

Have a nice day
Karsten
